GAETANO IMPELLITTERI AND ANTONINO IMPELLI'ITERI, OF NEW YORK, N. Y.

NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Application filed January 3, 1913. Serial N 0. 739,991.

To all whom, it may concern:

Be it known that we, GAETANO IMPELLIT- TERI, a citizen of the UnitedStates, and AN'roNINo IMPELLITTERI, a subject of the King of Italy, bothresiding in the city, county, and State of New York, have inventedcertain new and useful Improvements in Non-Refillable Bottles, of whichthe following is a full, clear, and complete disclosure.

Our invention relates to bottles of the kind comprising check valvesarranged to permit the liquid to fiow in only one direction, and has forits object the construction of a bottle of this kind, which will bereliable in operation, which will comprise but few parts, and which maybe cheaply constructed and will be neat in appearance.

In the drawing accompanying and forming a part of this specification wehave illustrated one embodiment of our invention and our improvementsand their advantages will be readily understood from a description ofthis embodiment.

Figure 1 of this drawing is a verticalsection of the device. Fig. 2 isan external view of the cap, valve-cage, valve-stem and adjustable stop,shown separately for clearness of illustration. Fig. 3 is a sectionalView taken on the line 33 of Fig. 1.

In the drawing, the numeral 1 designates the neck of a bottle, providedwith an outer annular shoulder 2.

The numeral 3 designates a cap fitted on the neck and having a dependingskirt or wall 4 fitting snugly around the neck and turned in behind theshoulder 2, so as to hold the cap in position. The cap comprises avertical tubular discharge extension 5, having an opening 6 therein,through which the liquid is discharged. The opening 6 may be providedwith a stopper or cap of any ordinary kind. At its lower end the opening6 communicates with an enlarged opening 12, the walls of which arethreaded so as to receive the threaded removable valve cage 7. The valve8 is mounted in the cage 7 and has a screw-threaded stem 9 having anadjustable stop 10 mounted thereon.

This stop regulates the distance which the valve may open and isadjusted when the cap is put in position. This adjustability is adesirable feature, since, by adjusting the stop 10 before applying thecap to the bottle any desired rate of discharge may be obtained. Inpractice the size of the discharge orifice 6 and the tubular extensionmay be varied with different uses but we prefer to have the openingelongated and contracted as it makes it more difficult for thoseattempting to refill the bottle to interfere with the normal operationof the valve. The side wall 4: in practice is made to extend below' thevalve cage and valve mechanism so as to obscure these parts and make amore sightly arrangement.

In operation, when the bottle is inverted, the valve opens and theliquid fiows out through openings 11, and through the valve port andopening 6. When the bottle is seated normally in an upright position,the valve is closed and liquids cannot be poured into the bottle. Whenthe bottle is inclined or laid on its side, the slightest efiort tocause liquid to flow into the bottle will close the valve and preventthe bottle being filled. After the contents of the bottle has been used,the cap may be destroyed while the valve and valve cage can be screwedout and used in a new cap.

In practising our invention, the body of the cap may conveniently bemade in one piece of britannia metal or other similar composition, asmay also the valve mechanism, though the latter parts should preferablybe made of harder material.

While we have described only one embodiment of our invention. we areaware that this may be modified by those skilled in the art withoutdeparting from the scope of our claim.

What we claim is:

In a non-refillable bottle, the combination of a cap having a side wallengaging the outer surface of the bottle neck, a contracted tubulardischarge orifice, a valve cage located in and having a screw-threadedengagement with the inner walls of said cap Patented June 24, 1913.
